Reaction Steps

Intermediate obtained from Step C was hydrogenated for 1 hour in EtOH (5 ml) in the presence of Pd(OH)2/C (0.015 mmol). The catalyst was filtered off through Celite® pad and ethanol was removed under reduced pressure. The crude reaction mixture was used in the next reaction without any purification.
